Skip K-a-l-i. I'd go straight to release of Ubuntu 16.04 LTS, and then set up using these instructions: https://hashcat.net/faq/wrongdriver ... and this version of the drivers directly from AMD:...

If you really think that your target plaintext is 32 digits long, you will need more information about digit placement and likelihood to have any hope of cracking it. To answer the literal part of yo...

I think they're trying to replace digits in place, without having to know the text before and after in advance.

It's possible that hashcat's format is a little different in its conversion, but I'm not sure what the difference might be. It's also possible that it's a slightly newer version or variant. Do you...

Huh - if the trial copy produces hashes of the same type, then this may indeed simply be a new variant. Please create an issue on hashcat's GitHub here: https://github.com/hashcat/hashcat/issue...

FWIW, for some attacks I've seen it's good to have one core per GPU. I haven't seen anything that would benefit from multiple cores per GPU.
